LSAW STEEL PIPE

LSAW Steel Pipe is made by hot rolled thick steel plate, this steel plate put into the mold or molding machine pressure (volume), using double-sided submerged arc welding and flaring processes.
Features: weld toughness, ductility, uniformity and dense, large diameter, thick wall, high pressure resistance, low-temperature corrosion resistance. Used in the construction of high-strength, high toughness, high-quality long-distance oil and gas pipelines.

In addition, We also manufacture ERW (Electric Resistance Welding) and SSAW (Spiral Submerged Arc Welding), so you can decide which type is better for your construction project.

BENDING MACHINE

UOE BENDING MOLDING

Our factory use “UOE” molding method, leaflets steel plate after the edge preflex.

U-FORMING

U-FORMING

We use U-forming machine produce line to make the thick steel pipe into “U-Shape” at first.

O-FORMING

O-FORMING PROCESS

After the “U-Forming” process, the raw material will be transport into the “O-Forming” machine produce line.

FINAL WELDING

Longitudinal Submerged Arc Welded

We will see the circular section after “O-Forming”, and then is the final process- inner welded and outer welded.
